Helgoland was an underwater laboratory where saturation divers lived and worked for weeks at a time. Sized only at 14 meters long, 7 meters wide and 7 meters high, you can imagine the living conditions down there. I suspect it was very cold, damp, dark and claustrophobic. The lab operated for a brief period of time in the mid seventies close to Jeffery's Ledge, several miles east of Rockport MA in Stellwagen Bank National Marine Sanctuary. In addition to studying herring, the scientists on board also researched saturation diving techniques. The lab is now retired to Germany (its home country) as a museum piece.
Diving this historical site has been a priority for me even though the lab itself is no longer there. There are old mooring blocks, anchors and several other artifacts left behind from the experiments. This past weekend, a handful of divers finally got to dive the site. Capt. Steve Smith of Cape Ann Divers was able to anchor us somewhere within the site. I say "somewhere" as I'm not yet even remotely familiar with the area. At 115 FSW, there is no time to mess around. On the preliminary checkout dive, current was strong but manageable. Unfortunately, it never tapered off in the deeper water, so we were working fairly hard throughout the dive.concrete mooring stone
As evident in the photo, visibility easily exceeded 40'. I recall seeing the bottom far below me during my descent. The bottom composition is beach-ball sized granite cobble. There was an incredible assortment of badge stars and northern red anemones growing on the rocks. In the very small area that we covered, we were able to find a mooring stone left over from the experiments. However, we burned through our bottom time in minutes and it was time to head back up. Ocean conditions prevented us from making a second dive. This is not the easiest location, but a very intriguing site and I can't wait to return. Next time we will know a little more of what to expect and hopefully we can help document more of the history of the ambitious Helgoland project.
